4 Claims.

This invention relates to mechanism for pegging lifts to shoe heels.

The invention has for an object to provide a novel mechanism adapted to automatically and simultaneously cut a plurality ci metallic pegs from running lengths of wire, .thereupon positioning the several cut pegs in properly grouped and spaced relation for insertion through a lift and into a heel body to which the lift is desired tc vbe pegged, and finally driving the pegs home through the lift and into the heel body.

The invention has for a further object to provide man automatic mechanism for the above stated purposes, a novel means for feeding continuous lengths of wire to the peg cutting means in timed relation to the operations of the latter. The invention has for another object to provide an automatically actuated cutting means which'y functions both to cut the metallic pegs from supplied wire and at the same time to carry the cut pegs into properly grouped and spaced relation for application to a lift and heel body.

The invention has for another object to provide a novel driving means to operate upon the entire group of pegs so as to simultaneously drive the same home through the lift and into thekshoe heel body; means being provided to actuate the driving means in properly timed relation to the operations of the peg cutting` and positioning means. f

A further object of the invention is to providev means for holding the lift and heel subject to the pegging operations, including an automatic heel clamp having means to actuate the same in timed from the following detailed description of the f same.

An illustrative embodiment of the novel machine according to this invention is shown in the accompanying drawings, in which- Fig. l is a front elevation of the machine; Fig. 2 is a fragmentary vertical longitudinal section thereof, drawn on an enlarged scale; Fig. 3 is a fragmentary horizontal section, taken on line 3 3 in Fig. 2; Fig. l is also a fragmentary hori- V zontal section, taken on line l-G in Fig. 2; Fig. 5 is a fragmentary vertical longitudinal section, showing a portion .of the wire feed actuating mechanism, said section being taken on line 5 5 in Fig. 4; Fig. 6 is a fragmentary transverse vertical section, showing a portion of the heel clamping means, said view being taken on line 6 5 in Fig. 1; and Figs. 7 and 8 are fragmentary longitudinal` vertical sectional views, respectively showing successive stages in the operations of the peg cutting and positioning means and the peg driving means.

Similar characters of reference are employed in the hereinabove described views, to indicate corresponding parts.

Referring to the drawings, the reference character i@ indicates a base or supporting framework of suitable design, upon the top plate II of which is supported, by longitudinally disposed sleepers i2, a bottom deck plate l, an intermediate'deck plate ii'and a top deck plate i5. The several deck plates are supported in suitably spaced superposed relation by corner posts I6.

The reference character i7 indicates a longitudinally disposed main shaft. This shaft is journaled at its outerfend portion in bearings I8 which are mounted on an extension l@ of the frame-work it, and the inner end portion of said shaft extends beneath the bottom deck plate I3, said inner end portion thereof being journaled in t -ta-bly disposed bearings 2t which are dependent frc-msaid bottom deck plate i3. Axed upon the outer end of said shaft il is a pulley 2 l or equivalent means, by which vthe shaft may be driven from any suitable source of power.

J oin'naled in and between said bottom and intermediate deck plates i3 and ie are suitably dis- Y,

bled together and aiixed to the upper side of said intermediate deckplate la. Timed reciprocation of each cutter plate 25 is produced by a cooperating actuating vcam 28 with which each driven shaft 22 is provided. These cams Z8 engage roller studs 25% with which the outer or tail end portion of each cutter plate 25 is provided. Each cutter plate is yieldingly retracted by spring elements Sii, whereby the roller studs 29 thereof are retained in operative engagement with the corresponding actuating cams 2B. The forward inner endv portion of each cutter plate is provided with a group of suitably spaced and disposed vertical passages 3! to receive the wire material from which the pegs are tc be cut. Imbedded in the intermediate deck plate 4, beneath each cutter plate are groups of correspondingly spaced and disposed stationary cutter blocks 32 having vertical wire passages 33 with which the passages 3| of the cutter plates align themselves when said cutter plates are retracted to normal initial positions. The cutter plates 25 are made of hardened steel, and the cutter blocks 32 are likewise made of hardened steel, whereby the meeting edges of the respective passages Ble-33 thereof will function as wire shearing or cutting edges when the cutter plate passages are forwardly moved across the stationary passages of the cutter blocks.

The top plate 21 of the slideway means in which the cutter plates move is provided with groups of correspondingly spaced and disposed vertical peg guiding passages 34 with which the respective groups of cutter plate passages 3| align themselves when said cutter plates 25 are actuated to cut pegs from the wire material fed thereto and thereupon move the cut pegs to positions wherein they are subject to the operations of the peg driving means of the machine.

A wire feeding means is provided to serve each cutter plate 25 of the peg cutting and positioning means. Mounted on the bottom decl.: plate I3 are laterally spaced standards 35 having bearings 35 in which are journaled the shafts 31 of the respective wire feeding means. Each wire feeding means comprises a feed roll 3B fixed on a shaft 31. Each feed roll is provided with spaced circumferential wire engaging channels 39, which correspond in number to the number of peg cutting and carrying passages 3| with which the cutter plate 25 to be served thereby is provided. Cooperating with each wire engaging channel of the feed roll 38 is a tensioned gripper roller 40. Each gripper roller 4|) is mounted on the end of the upwardly extending arm 4| of a plvoted bellcrank lever 42, to the outwardly and oppositely extending arm 43 of which is connected a suitably anchored spring element 44 which yieldably rotates the bell-crank lever 42 to tensionally press said gripper roller toward the feed roll 38.

Wire material 45 is led from suitably located and supported supply spools 46 to extend over suitably located and supported guide rollers 41, so that the strands thereof are caused to respectively pass around the feed rolls 33 and between the latter and said cooperating gripper rollers 40. The strands of wire material are engaged by the channels 3S of said feed rolls, and the surfaces of these channels, as Well as the surfacesl of the gripper rollers 4Q are preferably roughened, as by nurling, so that the wire strands will be effectively gripped by and between said feed rolls gripper rollers so as to be forwardly impelled toward the cutter plates 25 when said feed rolls are moved. From the feed rolls 38, the wire strands respectively eX- tend upwardly to and through the cutter block passages 33, and into the aligned cutter plate passages 3|, when the cutter plates 25 are retracted to normal initial position, and the feed rolls 38 are moved to feed the wire strands into such operative relation to said cutter plates 25.

The means for producing timed operation of the feed rolls 38 in proper relation to the controlled reciprocatory movements of the cutter plates 25, comprises intermeshing gears 48 by which rotation of one shaft 3l.' is transmitted to the other. Aflixed to one of said gears 48 is a ratchet gear 49, and pivoted upon the shaft of such gear 4B is an oscillatable arm 5S upon which is mounted a spring pressed pawl 5| adapted to operatively engage said ratchet gear 4B, Timed oscillation of said arm and pawl is controlled by a cam 52 which is mounted on said main shaft l1. Supported in bearings 53 adjacent to one side of said bottom deck plate is a rock-shaft 54, and aiiixed to said rock-shaft is a lever member 55 adapted to be operatively engaged by said cam 52. Preferably the cam engaging end p0rtion of said lever member is provided with contact roller 55 to assure an anti-friction engagement of these parts. Also aixed to said rock-shaft 54 is a lever arm 51, the free end portion of which is connected by a link 58 with the free end portion of said oscillatable arm 5U. Aflixed to said rock-shaft 54 is a crank-arm 5S, to which is connected a suitably anchored spring element Eil, which yieldably retains the above described transmission means under the control of the actuating arm 52.

The means for driving home the pegs into the work, after the same has been cut and positioned by the cutting plates 25, comprises a vertically reciprocable driver plunger 5| which is slidably supported below said intermediate deck plate I4 in a guide casing 62 which is affixed to and supported upon said bottom deck plate |3. The lower end of said driver plunger 6| extends downwardly through the bottom deck plate i3 so as to be operatively engaged by an actuating cam 53 which is mounted upon and rotated by said main shaft I1. Preferably the cam engaging end of said driver plunger 5| is provided with a contact roller E4 to assure an anti-friction engagement of these parts. A spring means 85, disposed between the under side of said intermediate deck plate |4 and an axial receiving socket 65 with which the driver plunger is provided, serves to yieldably retain said driver plunger under the control of its actuating cam 63. AfXed to the upper end of said driver plunger 6| are a plurality of 11p-standing driver rods 61 which correspond in number and position to the number and position of the pegs as cut by the cutter plates 25 and then delivered to positions ready to be driven into the work. The intermediate deck'plate |4 is provided with vertical slideways 68 which are aligned with the peg guiding passages 34 with which the top plate 21 of the cutter plate slideway means is provided.

The upper free end portions of said driver rods 61 are disposed within and are guided during operation by said slideways 68.

Means are provided for positioning and holding the work upon the top plate 21 and over the peg guiding passages thereof. This cornprises a lift holding plate 69 which is affixed to the top-plate 21. This lift holding plate 53 is provided with an opening 1G shaped to conform substantially to the peripheral shape of a heel lift 1|, thus providing a receiving socket within which the latter may be deposited and by which it may be held in proper position to receive insertion therethrough of the groups of cut pegs by which the same is to be pegged to an overlying heel body 12, when the latter is applied over and registered with said lift.

Means are provided for automatically clamping a heel body 12 upon the deposited lift 1| which is desired to be pegged thereto. This clamping means comprises a vertically reciprocable clamp plunger 13 which extends slidably through the top deck plate I5 in alignment with the lift socket of the lift holding plate 69. The means for producing properly timed operation of said clamp `is to be pegged to the heel body l2.

plunger 'i3 comprises a longitudinal rock-shaft 'illjournaled in bearings l5 mounted upon the top deck plate l5. Affixed on said rock-shaft lll is a clamp plunger actuating cam 'l5 to operatively engage the upper end of said clamp plunger i3. Preferably upper end of said clamp plunger i3 is provided with a contact roller 'il to assure an anti-friction engagement thereof by said actuating cam l5. Suitably connected with said clamp plunger 'i3 are suitably anchored spring elements it which yieldably retain the clamp plunger 'i3 under the control of said actuating cam ld. Mounted on the main shaft il is operating cam i9 which serves to produce and properly time the oscillations of said rock-shaft lil and clamp plunger actuating carol'. Pivotally connected with the frame-work extension i3 is a lever member 3d, which underlies and is operatively engaged by said operating cam Preferably said lever n ember il@ is provided with a suitably mounted and located contact roller di to assure an anti-friction engagement 'thereof by said operating cam it. Suitably anchored spring means Si. is connected with said lever member 8i! to yieldably retain thev same under the control of said operating cam "it, .Alixed to the roel;- shaft l'l is a lever arm 33, and interconnected between said lever member dll and lever arm 83 is a spring compensated linl; rod means. This link rod means lcomprises a lower linlr rod section Silpivotally connected by its lower end to said lever member 8d and having in affixed relation to its upper end a cylinder member t5. Pivotally connected by itsupper end to said lever arm S3 is an upper rod section 3@ having at its lower end a piston head slidably engaged in said cylinder member 85; said rod section slidably extending through the upper end cap t8 of said cylinder member 35. Engaged around said upper link rod section between the piston head B7 thereof and the upper end cap it of the cylinder member B5, is a compression spring Sil.

In the operation of the machine, a lift ll is deposited within the holding plate 69, whereupon a body l2 to which the lift is to be pegged is superimposed upon the lift 'il in properly aligned relation between the same and the raised clamp plunger i3. While the cutter plates 25 occupy retracted positions, in which their wire passages Si are aligned with the passages 33 of the cutter blocks (as shown in Fig. 2), the wire feeding means, by the timed operation thereof as controlled by the cam 52, is operated to effect a rotative movement of the feed rolls 38 which advances the upper end portions of the wire strands le upwardly through the cutter block passages 33 and into cutter plate passages El until stopped by engagement with the under side of the slideway top plate .''i. Rotation of the cutter plate '1. actuating cams 28 operates to advance or move inwardly the cutter plates 25. Such movement of the cutter plates shears away the end portions of the wire strands engaged in the passages 3i thereof, thus producing the pegs eil by which the lift l The inward movement of the cutter plates carries the cut pegs @il into alignment with the peg guiding passages 3@ of the slid-away top plate 2l', thus positioning the pegs beneath the lift ll in the desired grouped and spaced relation as predetermined by the number and grouping of said cutter plate and top plate wire passages. When the pegs 9G are thus moved into position ready to be simultaneously driven through the lift 'il and into the heel body l2, said pegs will also be aligned with the ends of the corresponding grouped and guided driver rods 6l of the driver plunger 6I, which, while the pegs are moved into position, remains downwardly retracted (see Fig. 7)

In the meantime, the clamp plunger13, under the timing control of the actuating cam i9 and intermediate operating mechanism, is caused to descend and thereby engage the heel body 'I2 so as to firmly hold the same against displacement, and also properly backed to withstand the thrust oi the pegs 95 when the latter are subsequently driven thereinto. Owing to the spring compensated link'rod structure which connects the cam actuated lever 88 with the rock-shaft lever 83, the clamp plunger i3 and its operating mechanism will not only automatically adjust itself to diiferent heights of heel bodies, but the compression of said spring 8s, due to the excess throw of the lever 88, as compared with the maximum movement required of the rod-shaft lever 83 to effect maximum throw of the clamp plunger actuating cam '16, will exert a strong tensional pressure upon the latter parts, which will be in excess of resstance of the lift and heel body to the penetration thereof by the pegs at, when the latter are driven home, and consequently the heel body will be rmly and strongly backed against yielding to the thrust of the entering pegs.

The cams 28 which control the movements of the cutter plates 25 are so shaped as to cause the latter to dwell in their inwardly moved positions during the peg driving operations, and until after completion of said operations and retraction of the driver rods 67.

The cam 63 which controls the operation of the driver plunger l is so rshaped as to properly time the rise and fall of said driver plunger relative to the operation and dwell of the cutter plates 25.

While, therefore, the cutter plates 25 dwell in their inwardly moved positions whereby the pegs 9i) are held aligned between the guiding passages 34 and the driver rods 51, said cam 't3 operates to raise the driver plunger Eil. The upward movement of the driver plunger slides upwardly the driver rods Sl' which engage the lower ends of the pegs 99, and consequently the upward movement of the driver rods 6l, in turn drive upwardly said pegs su, thereby causing the latter to pierce the lift ll and penetrate the shoe heel l2, so that all the pegs are simultaneously driven home in a single stroke (see Fig. 8). After the pegs are thus operatively applied to the lift and heel body, the cam 63 permits the driver plunger and its driver rods to return to normal initial lowered position, whereupon the cams 28 return the cutter plates E5 to normal initial positions, following which the wire feeding means operates to again advance the wire strands into the cutter plate passages 3l, and the above described cycle of operations may be repeated.

It will be understood that the machine driving transmission may include any suitable trip clutch mechanism (not shown) whereby the main shaft il' is automatically stopped upon completion of one revolution.
